betta sorority. how many girls to add?

[dhjaksu]

how many female bettas should I put in a 55gallon/210litre tank? heavily planted and 4x the necessary filtration. with 6 corys and I'm going to get a group of 15 espei rasboras.

i am pretty experienced with bettas and have 7 girls in a 20 gallon tank and a few single girls and a few single males. im just not sure how many to put in a 55gal tank (the 7 already in the 20gal will be moved across. I can have anywhere from 13-28 girls (6 more have already been ordered. contemplating ordering another 15 after Christmas)

Ιt depends on your planting, really... lf super heavily planted, l'd say up to 30.

Remember though you must add them all at once. Adding new ones later is a recipe for disaster

its definitely heavily planted. this is the most recent photo I have but the plants have been trimmed and replanted a fair bit since as well as I've added more caves. And I'll probably order some new plants when I order the new bettas. My phone is broken so I can't take a current photo. this is from a few months ago. It pretty much looks like a dense jungle now.

and, yeah, I won't add the girls to the tank until I have them all.
